Cannabidiol or better known as CBD has turned out to be a rising star in the medical cannabis world. Several studies have shown it has medical benefits without giving you a “high.” One of its benefits is improving sleep pattern, and this may spark interest for those who have been suffering from insomnia.

What is the sleep cycle?

Sleeping looks simple, but it is actually a complex process. Sleep includes 5 stages, with the first four stages comprising the non-rapid eye movement and the last stage with rapid eye movement phase.

The sleep cycle takes 90 minutes to complete, and our bodies need between 4 and 6 cycles for an optimal duration over a 24-hour period. Also, an average adult needs 8 hours of sleep per night to function well and to avoid suffering from cognitive and physical side effects.

Insomnia is a condition characterized as an inability to sleep. When left untreated, it can result in several adverse effects such as poor sleeping habits, ineffective work performance, depression, and anxiety.

How will CBD help my insomnia?

CBD has been known to have beneficial and hypnotic effects that improve sleep pattern and quality. It interacts with different cell receptors, proteins, and chemicals in the brain. Such interactions change the activities of neurotransmitters, hormones, and other cells in a positive way.

Your body produces cannabinoids, called the endocannabinoid system. It is responsible for many bodily functions, including physiological processes and cognitive functions. CBD is capable of interacting with the system and the attached receptors to reduce physical and mental pain.

The calming effects of CBD also ensure that you sleep with a quiet mind at night. For instance, people suffering from REM behavior disorder are less likely to suffer from disruptive sleep and to inflict potential injuries on themselves.

In fact, a clinical review of 15 subjects suffering from insomnia revealed that a dose of 160 mg of CBD can improve the duration of sleep.

A more recent study also determined the disruptions in the circadian rhythm after taking CBD or THC. Results from the clinical trials revealed the therapeutic effects of CBD versus THC in treating insomnia and improving the circadian rhythm balance.

What are the side effects?

The good thing about taking CBD instead of your usual sleeping pills is the fact that CBD oil only has a few minor side effects. These include dry mouth, lightheadedness, and low blood pressure. According to the World Health Organization, CBD does not appear to cause harm or abuse potential. However, it should still be taken with caution.

CBD is not addictive, and it does not put you at risk for overdose. Prescription drugs, such as valium, for instance, is habit-forming and will eventually destroy your kidneys. Furthermore, sleeping pills tend to make you feel groggy in the morning.

People who are pregnant and breastfeeding may need to consult their doctor before using CBD. Also, if you are taking maintenance medications or other herbs and supplements, make sure you ask your doctor before taking CBD to avoid possible interactions.

How to take CBD for sleep?

When consumed in modest doses, CBD can be mildly alerting. CBD tends to activate the same adenosine receptors as caffeine, which is a stimulant. However, several patients have claimed that taking CBD tinctures or extract a few hours before bedtime can help them have a good night’s sleep.


Although many people are starting to use CBD as an alternative, more in-depth research and human trials are needed to assess its effectiveness in improving sleep pattern as well as treating insomnia and other sleep deficiencies. Again, it is best to consult your doctor before taking CBD.
